Title: Susceptor
Inventor: TAZOE HARUO
IPC: H01L21/205
Filed: 1989-12-27
Abstract: PURPOSE:To suppress the generation of pinholes by freely attachably and detachably providing a spot facing member provided with a spot facing part to be imposed with a wafer on the surface of a susceptor body. CONSTITUTION:SiC coating 3 having 50 to 200mum thickness is formed on the surface of the susceptor body 1 constituted of a carbon base material. The spot facing member 4 is freely attachably and detachably mounted to the susceptor body 1. The spot facing member 4 and the recessed part 2 of the susceptor body 1 are formed to the completely corresponding shape and there are no spacings at all between both. The spot facing member 4 constituted of only the SiC is formed to the tray shape of approximately the same thickness over the entire part. The spot facing member 4 is removed from the susceptor body 1 and is subjected to an etching treatment at the time of etching and therefore, the spot facing member 4 is not etched. The generation of the pinholes is consequently averted. The spot facing member 4 is made of single material and, therefore, the pinholes are not generated in the spot facing part 6 even if the spot facing member 4 is held mounted in the susceptor 1 and is subjected to the etching treatment in this state.

Title: Automatic document feeder
Inventor: ISEDA KEN
IPC: G03B27/62
Filed: 1989-12-27
Abstract: PURPOSE:To surely position a document at a prescribed position and to carry out an image forming action without having positional deviation by controlling a carrying means so as to reduce its carrying speed when a document reaches a prescribed position at a carrying action by means of the carrying means. CONSTITUTION:A pair of resist rollers 26 carry the document D carried by a first carrying means 25 so as to feed it between a movable platen sheet 13 and a platen glass 10, and a feeding roller 28 constitutes a position adjusting means 29 feeding the carried document D so as to face the prescribed position of the platen glass 10. When the tailing edge of the document D is detected by a second tailing edge detecting switch 29 arranged just behind separating/ feeding means 21 and 22, the carrying speed of the document D by a pair of resist rollers 26 is reduced. Therefore, the document D is prevented from passing through a first tailing edge detecting switch 37 for controlling the feeding roller 28 by inertial force. Thus, the document D is surely positioned at a prescribed position, an image forming action without having positional deviation can be carried out.

Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To miniaturize a camera by using a part of an optional field frame display part and a part of another field frame display part in common at the time of selectively inserting plural field frame display parts in a finder optical path. SOLUTION: A finder mask member 2 has three field frame display parts 2A to 2C, which are respectively provided with field frames 2a to 2c regulating a photographing range.
